Population genomic dynamics of mesopelagic lanternfishes Diaphus dumerilii, Lepidophanes guentheri, and Ceratoscopelus warmingii (Family: Myctophidae) in the Gulf of Mexico Deep Sea Research Part I: Oceanographic Research Papers (2022)
Assessing the impacts of the Deepwater Horizon oil spill (DWHOS) on deep-sea fish assemblages of the Gulf of Mexico (GOM) has been hindered by an absence of baseline (pre-spill) data concerning the population genetic dynamics ...
Three complete mitochondrial genomes of shortfin mako sharks, Isurus oxyrinchus, from the Atlantic and Pacific Oceans Mitochondrial DNA Part B (2022)
We present complete mitogenome sequences of three shortfin mako sharks (Isurus oxyrinchus) sampled from the western Pacific, and eastern and western Atlantic oceans. Mitogenome sequence lengths ranged between 16,699 bp and 16,702 bp, and all ...
Genomic assessment of global population structure in a highly migratory and habitat versatile apex predator, the tiger shark (Galeocerdo cuvier). The Journal of Heredity (2021)
Understanding the population dynamics of highly mobile, widely distributed, oceanic sharks, many of which are overexploited, is necessary to aid their conservation management. We investigated the global population genomics of tiger sharks (Galeocerdo cuvier), a ...
Sexual conflicts in sand tiger sharks Carcharias taurus (Rafinesque, 1810) in an artificial environment Journal of Zoo and Aquarium Research (2021)
Understanding reproductive behaviours and the environmental conditions that facilitate reproduction is important for successful reproduction in managed care. Complex reproductive behaviours have been observed in both aquarium and free-ranging elasmobranchs. Sexual conflicts, including pre-copulatory behaviours ...
Evidence of historical isolation and genetic structuring among broadnose sevengill sharks (Notorynchus cepedianus) from the world’s major oceanic regions Reviews in Fish Biology and Fisheries (2021)
Cosmopolitan marine pelagic species display variable patterns of population connectivity among the world’s major oceans. While this information is crucial for informing management, information is lacking for many ecologically important species, including apex predators. In ...
Come together: calibration of tiger shark (Galeocerdo cuvier) microsatellite databases for investigating global population structure and assignment of historical specimens Conservation Genetics Resources (2021)
This study provides the first standardized global microsatellite database for a shark species, the tiger shark (Galeocerdo cuvier). Genotyping of reference individuals was used to develop and apply a calibration key for data from eight ...
Microbiome Analyses Demonstrate Specific Communities Within Five Shark Species Frontiers in Microbiology (2021)
Profiles of symbiotic microbial communities (“microbiomes”) can provide insight into the natural history and ecology of their hosts. Using high throughput DNA sequencing of the 16S rRNA V4 region, microbiomes of five shark species in ...
A Multidisciplinary Approach to Investigate Deep-Pelagic Ecosystem Dynamics in the Gulf of Mexico Following Deepwater Horizon Frontiers in Marine Science (2020)
The pelagic Gulf of Mexico (GoM) is a complex system of dynamic physical oceanography (western boundary current, mesoscale eddies), high biological diversity, and community integration via diel vertical migration and lateral advection. Humans also heavily ...
Insights Into Insular Isolation of the Bull Shark, Carcharhinus leucas (Müller and Henle, 1839), in Fijian Waters Frontiers in Marine Science (2020)
The bull shark (Carcharhinus leucas) is a large, mobile, circumglobally distributed high trophic level predator that inhabits a variety of remote islands and continental coastal habitats, including freshwater environments. Here, we hypothesize that the barriers ...
Seasonal patterns in stable isotope and fatty acid profiles of southern stingrays (Hypanus americana) at Stingray City Sandbar, Grand Cayman Scientific Reports (2020)
Ecotourism opportunities in the marine environment often rely heavily on provisioning to ensure the viewing of cryptic species by the public. However, intentional feeding of wildlife can impact numerous aspects of an animals’ behavior and ...
The complete mitochondrial genome of a gray reef shark, Carcharhinus amblyrhynchos (Carcharhiniformes: Carcharhinidae), from the Western Indian Ocean Mitochondrial DNA Part B (2020)
We present the mitochondrial genome sequence of a gray reef shark, Carcharhinus amblyrhynchos (Bleeker 1856), a coral reef associated species. This is the first mitogenome for this species from the western Indian Ocean. The mitogenome ...
First Insights Into the Vertical Habitat Use of the Whitespotted Eagle Ray Aetobatus narinari Revealed by Pop‐up Satellite Archival Tags Journal of Fish Biology (2020)
The whitespotted eagle ray Aetobatus narinari is a tropical to warm‐temperate benthopelagic batoid that ranges widely throughout the western Atlantic Ocean. Despite conservation concerns for the species, its vertical habitat use and diving behaviour remain ...
Seasonal Movements and Habitat Use of Juvenile Smooth Hammerhead Sharks in the Western North Atlantic Ocean and Significance for Management Frontiers in Marine Science (2020)
Upper trophic level predators dramatically impacted by fisheries include the large-bodied hammerhead sharks, which have become species of conservation concern worldwide. Implementing spatial management for conservation of hammerhead populations requires knowledge of temporal distribution patterns ...
Restricted Connectivity and Population Genetic Fragility in a Globally Endangered Hammerhead Shark Reviews in Fish Biology and Fisheries (2020)
Vagile, large-bodied marine organisms frequently have wide range dispersion but also dependence on coastal habitats for part of their life history. These characteristics may induce complex population genetic structure patterns, with resulting implications for the ...
Spatio-Temporal Genetic Tagging of a Cosmopolitan Planktivorous Shark Provides Insight to Gene Flow, Temporal Variation and Site-Specific Re-Encounters Scientific Reports (2020)
Migratory movements in response to seasonal resources often influence population structure and dynamics. Yet in mobile marine predators, population genetic consequences of such repetitious behaviour remain inaccessible without comprehensive sampling strategies. Temporal genetic sampling of ...
Analysis of surfactant-associated bacteria in the sea surface microlayer using deoxyribonucleic acid sequencing and synthetic aperture radar International Journal of Remote Sensing (2020)
The sea surface microlayer (SML) is the upper 1 mm of the ocean, where Earth’s biogeochemical processes occur between the ocean and atmosphere. It is physicochemically distinct from the water below and highly variable in ...
Genetic and Biophysical Modelling Evidence of Generational Connectivity in the Intensively Exploited, Western North Atlantic Red Grouper (Epinephelus morio) ICES Journal of Marine Science (2019)
Understanding the connectivity of reef organisms is important to assist in the conservation of biological diversity and to facilitate sustainable fisheries in these ecosystems. Common methods to assess reef connectivity include both population genetics and ...
The Complete Mitochondrial Genome of an Atlantic Ocean Shortfin Mako Shark, Isurus oxyrinchus Mitochondrial DNA Part B: Resources (2019)
We report the first complete mitochondrial genome of a shortfin mako shark from the Atlantic Ocean. The genome had 16,700 base pairs and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a ...
Global Spatial Risk Assessment of Sharks Under the Footprint of Fisheries Nature (2019)
Effective ocean management and conservation of highly migratory species depends on resolving overlap between animal movements and distributions and fishing effort. Yet, this information is lacking at a global scale. Here we show, using a ...
Behavioral Response of a Mobile Marine Predator to Environmental Variables Differs Across Ecoregions Ecography (2019)
Animal movement and habitat selection are in part a response to landscape heterogeneity. Many studies of movement and habitat selection necessarily use environmental covariates that are readily available over large‐scales, which are assumed representative of ...
Genetic Connectivity Dynamics of the Giant Barrel Sponge, Xestospongia muta, Across the Florida Reef Tract and Gulf of Mexico Bulletin of Marine Science (2019)
